H. B. RAMSEY, OF INDIANAPOLIS, INDIANA.

. BRICK-MACI-LINE.

Specification of Letters Patent No. 15,618, dated August 26, 1856.

To all whom t may concern Be it known that I, H. B. RAiusEY, of, Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Machine for Making Brick; and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawings., making a part of this specilicatio-n, in which- Figure 1 is a perspective view showing the different parts of the machine and their general arrangement.

a, is a wrist to which the driving power may be applied to the fly-wheel 1, which is `upon the shaft` 2, upon which are the drum 3, (upon which the band 4 runs) the cam 5, (which works the pump 6 for the purpose of supplying the regulating water cistern W, in the top of the clay-box 10. Said cistern has a double perforated bottom, the holes in which are closed or opened by revolving the upper plate of the same,) and the cogwheel 7 which is geared into the cog-wheel 8, which turns the shaft 9, (upon which arethe knives k, 7c, lc, la, lo, 7c, lo, 7c, 7c, 7c, la, 7c, which revolve between the rods r, r, r, 1', r, r, r, 1", r, 1, r, r, which are fastened into the clay boX 10, at o, e, o, e', o', fv, o, o, o, e, o, fu, running nearly to the center or shaft 9 for the purpose of grinding the clay,) and the cog wheel 11, which turns the shaft 12, upon which are the cog-wheel 13, (which is geared into the cog-wheel 14, which drives the drum 15 upon which runs the elevator band 16, around the drum 17, for the purpose of conveying the clay from the bank, which clay is emptied into the clay box 10, through the hopper 18) and the drum 19, around which the band 20, passes to the drum 21, which drives the drum 22, (which is upon the same shaft,) around which the cleated band c, Z), passes to the drum 23, for the purpose of conveying the molds m, from the yard to the machine upon the railway 24.`

The band 4 passes around the drum 25, which is upon the same shaft with, and runs, the cog-wheel 26, which gears into the cog-wheel 27, the workings of which may be seen by reference toV Figs. 2, 4 and 3, of which the following is a full and complete description.

Figs. 2 and 3 are views of detached parts in which A, is a cog wheel the same as in `lever Y, which works upon the roller r, `in the knuckle-joint P (which is permanently fixed at the bottom) is pressed up by the goose-neck lever Y. The slides N, N, are made fast to the top of the knuckle- "joint P, by wrists at X, X, and are raised by the knuckle-joint P.

Upon the top of the slides N, N, is the mold table T, upon which the molds J, J

i rest and are raised to the knives K, K, which are made to pass over the top of the molds by the springs S, S, as will be shown.

The arm C, is made fast to the wrist at B. Attached to the arm C, is a wrist at F, upon which the pitman 2 works. The pitman 2, is attached to the goose-neck lever z.. The goose-neck lever h works the roller It, which is attached to the lever L, by

which the reciprocating ear I, to which it is att-ached, is moved as will be shown.

The arm D is made fast to the outside of the wrist F, and extends to a point over the center of the cog-wheel A. At this point, the .shaft E, is attached forming a center upon which the cog-wheel A revolves.

Upon the ends of this shaft are the cranks G, G, upon which the pitmen 3, 3, work. The pitmen 3, 3, are attached to the catches mi, m, for the purpose of holding and letting go the springs S S as will be shown.

The following is a description of the workings of the above described parts of this brick machine. As the cog-wheel A revolves and the grist B, is moved toward the knuckle-joint P, the knuckle-joint P is straightened, raising the molds J, to the knives K, K. At the same time that the wrist B, is moved toward the knuckle-joint P, the wrist F, draws the reciprocating car I, back by means of the pitman 2, the gooseneck lever h, and the lever L. The cranks attached by joints at 0;, a, to the bottom of the springs S, S. The springs S, S, work upon flXed pivots at B, B. At the raising G, G, also move back the pitmen 3, 3, and

ilo

of the slides N, N, the springs S, S, are forced out by the pitmen Z, Z, moving the top of the spring in, and the knives K, K,

(to which they are attached,) across the top of the molds J. The springs S, S, are held back by the catches m, m, until the proper time for cutting the clay as heretofore described. Fig. 5, is a perspective View showing the general arrangement of the machine, and designed to assist in explaining Fig. 1.

What I claim and desire to secure by Letters Patent is l. The Wheel A, cranks Gr, Gr, and catchesm, m, in combination With the springs S, S, for the purpose of regulating the stroke of the knives K, K, for cutting the clay, at the top of the molds J, as described and shown.

2. I claim the sliding mold table T, for the purpose of raising the molds to the grate under the clay box, When the same is constructed, arranged, and operated in the manner and for the purposes set forth.
